BLUE-PBINT-WASHING MACHINE.

Specification of Letters Patent.

Patented Jan. 7, 1919.

Application filed June 9, 1917. Serial No. 173,866.

To all whom it may concern:

Be it known that I, WILLIAM M. DWYER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Blue-Print-Washing Machines, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in blue print washing machines.

In the washin and fixing of blue prints, considerable difficulty has heretofore been experienced in properly uniformly washing.

the blue prints and properly uniformly applying the potash solution and furthermore, painful injuries have sometimes been occasioned to the operators due to contact with the potash solution while handling the wet blue prints.

1 The object of my invention is to provide a blue print washing machine of simple construction and so arranged as to promote uniform washing of form application of the fixing solution and without the necessity of the operator touching the paper after it is wet.

In the drawing forming a part of this specification, Figure 1 is a side elevation ofv a machine embodying my improvements. Fig. 2 is an end elevation of the machineillustrated in Fig. transverse section of the upper portion of the machine illustrated in Fig. 1, and taken on the line 3-3 thereof. Fig. 4 is a detail view of one of the water spraying pipes. Fig. 5 is a broken view similar to Fig. 2 illustratinganother embodiment of the invention.

Fig. 6 is a sectional view similar to Fig. 3 illustrating a still further embodiment of the invention. I

Referring first to the construction illus- 2 and 3, the machine is shown as oomprising'sheet metal ends 10-10 tapered in their upper portion as indicated at 11-11, said ends being mounted on snift e latter being adapted to rest upon the floor. The ends 10'-1O are maintained in their proper spaced relation by means of longitudinally extending bars 13-13 at the bottom, the bars 13 being also oscillatable in suitable pair of wings the entire sheet and uni- 1. Fig. 3 is a VGI'tlCZLl bearings 14c, and a pair of longitudinally extending water spray pipes 15-15 near the top thereof. Mounted between the ends 10 of the machine, near the top is a clamping table having a central ridge 16 and oppositely downwardly inclined surfaces 17-17. To the lower edges of each of the inclined portions 17 is attached the upper edge of a metal sheet 18 which is downwardly curved at a steeper inclination, as clearly appears from Fig. 3, each of the sheets 18 terminating along a line indicated at 19. Below the line 19, another sheet 20 is extended downwardly in the same plane as the corresponding upper sheet '18, the sheets 20 terminating at their lower edges, as indicated at 21, in a large trough 22, the latter having a drain pipe 23 leading therefrom, as clearly indicated in Figs. 1 and 2.

Cotiperable with the inclined table portions 17, are longitudinally extending clamping plates 243-2 1 mounted on the ends of a 25 pivotally mounted about a central longitudinally extending axis 26. In Fig. 3, two blue print sheets 27-27 are shown in clamped position between the clamping plates 24 and the respective inclined beds 17. It will also be noted that the water spray pipes 15 have the spray holes 28 thereof so positloned as to direct a plurality of fine streams of water 29 on to the uppermost exposed portion of the blue prmt sheets.

To operate the clamps 24:, each of the rods 13 at the bottom of the machine is provided with a plurality of levers 30 having a foot treadle 31 secured thereto at their outer ends. Also connected to each of the rods 13, on the outside of the ends of the machine, are inwardly extending levers 32, each of which is pivotally connected to an adjustably connecting rod 33. The rods 33 are pivotally connected at their upper ends, as indicated at 34, to the ends of the respective clamping plates 24, the latter having brackets 35 from which extend short studs 36 engaging in eyes at the upper ends of the links'33. In this connection, the ends of the machine are suitably slotted as indicated at 37, to accommodate the movements of the brackets 35. Each of the connecting rods 33 extends through a bracket 38 near the bottom of the machine and against which bears one end of a sprlng39, the opposite end of thesp'ring 39 being held by a pin or other suitable device 40 on the connecting rod.

With the arrangement above described, it is apparent that the springs 39 will act against the rods 33 to hold the clamping plates 24 normally down. Vhen it is de sired to insert the edge of a blue print in.

trough 22, as clearly illustrated in Figs. 1

As will be understood, the blue prints are placed in the machine while dry andafterthe same have been thoroughly washed, it is'then necessary to apply the fixing solution o'ffpotash which. the operator can readily do by means of a brush, and in this connection it. will be understood that a firm backing for-the entire blue print is provided by the sheets 18" and20, thus insuring a uni form'application ofthe fixing solution.

Afterthe blue print has again been Washed, it is necessary that the same be removed from the machine" and without theoperator coming in contactwith the chemicalsemplo-yed'. To accomplish this result, a pair of inclined guide-ways 42- 12 are formed, down which a plurality of rods 43-43 are adapted to gravitate, said rods 43 being inserted through suitable openings At the in the end walls of the machine. bottom of each; of thegravity run-ways 42,

a'shou-l der 4'5 is provided, whichcatchesthe lowermost rod therein. When the blueprint is tobe-removedf from the machine, the oper-- ator gripsthe lowermost rod43 in back'ofthe blueprint'and pulls theblue print outwardlyby said rod, thus folding the blue print part-ly'overth'e rod. Vith the blue print-thns caught on the rod, the correspjon'ding clamp 24:- is released by depress- 'lfigiftl'lfi t 'readlie 31 and theblue print" thus removed 'fromt themachine without the; op

erator coming into'contact therewith. The rods 43 will be'madeof a length slightly less than the distance between .the ends 10 of the machine but longer than the-blue pr-int" and accesste the endsof the' rods isi perinitted by cutting away-the shjeets' 1 8' at the places indicated at-46in Fig. 1. In order to maintain the-supply of'ro'ds43, the operator will place the same--in the machine through the openings as fast as the same are taken :from' dry prints.

With the arra ngement shown in Figs; 1,

2 and 3, the-machine can be operated from both'sides simultaneously, thus obtaining a maximum capacity, or one side can be operated at-a time, if desired.

In the construction illustrated in Fig. 5, the arrangement is quite similar to that illustrated in Figs. 1, 2 and 3, except thata single water spray pipe 114; is employed instead of two of such pipes. Said spray pipe 114 is mounted on a swinging arm 50 which is pivoted about an aXis 51 at the top of the machine. The l'ever50 isadapted to be swung back and forth by" means-of an operating handle 52 which is pivotal-ly attached'to a bracket 53 thatin turn is secured to the upper pipe 51. Adjustable stops 5-1 are provided on the end of the machine against w-l'iich-the handle 52 rests in theopcrating positions of the spray pipe 114-. The arrangement of clamps and foot treadles for operating the same is similar to those in Figs. 1, 2 and 3. In operating the machine illustrated in Fig. 5,- when a blue print is finished, the operator swings the spraypip'e'to th'e opposite-side and then releases the blue print and takes it out of the machine. by means of a rod, as heretofore described;

In the construction illustrated in Fig; 6, the spray pipe 214 is mounted at the-lower end of a swinging lever pipe 250 that in' turn is secured at its upper end to-ani oscillatable pipe 251 mounted in suitable bearings supported 1 on :the machine. In. this ico'nstru rt i on, only one blueprint 227' at a time can be washed, thelsamexbeing'held by a clamp 224- p'ivot'a-lly mounted. on" a longitudinally extending'rod 226,-.tl1e-elamp 224-being held down undennorma'l conditions by means of suitable spring 39. From the clampv 224 extends an ofl-set-:1ever'61Whieh is'adapted to be engaged by the-spray pipe 21 i as the latter is. swung rearwardly. The dotted linesiinFig. 6 indicate the manner of releasing the clamp 224 by swinging, the: spray pipe 214:.v Thepipe214 is swung by means of a. suitable: foot-treadle which actuates a connecting rod. 233 that in. turn ispivoted tot-a lever? 62aclampedutothepipe 251.
